Calls from the mobile are sent to the hostname specified, using the username and password specified. The called number is the dialled number from the phone. The CLI is the SIM's ICCID. The call comes from the same group of call servers and will normally be from the same IP address from which the registration request is sent.
All calls each way are UDP SIP/2.0 control messages with G.711 64kbs a-law audio. The service uses DNS
* The CLI for calls to a mobile should be sent as a full international number without the leading +. Other formats will work, but are likely to present with a + and the digits sent. This is an area we want to improve over time. You can, however, present any CLI.
